Description of the disease (onset time, main symptoms, hospital, etc.): Dr. Liu: Hello, my daughter is 13 years old, this year, milk teeth just fell out, the teeth grow more neat, just slightly blemished incisors to the outside. Listen to others say, some orthodontic also need to extract the teeth, the cost of more than 10,000 yuan. What is the best age for orthodontic treatment? We have limited financial resources, so I wonder if simple orthodontic treatment like my daughter’s is also expensive. Hello! Please forgive me for not being able to reply online in time due to the National Day vacation! Most of the time, the time for orthodontic treatment is just after the replacement of milk teeth and the eruption of permanent teeth, but in some cases, this is not the case. Age is only a reference, we are more interested in the age of teeth and bone. There are some malformations that need to be treated as soon as they are born, and there are others that must be treated in adulthood, i.e., after the age of 18 or 19, so it is important to be evaluated by an orthodontist in a timely manner in order to avoid missing the optimal time. The patient’s perception of the difficulty of treatment is not always the same as the real difficulty of treatment, or even the opposite, so it is advisable to seek an evaluation by your orthodontist. Regarding the cost of orthodontic treatment, there are a lot of options, and not all of them are as expensive as you make them out to be. I will be available all day next week, Tuesday, Thursday and Saturday, so feel free to bring your child in for a consultation.
